Red green colorblindness is a disorder in which person is not able to distinguish between red and green color.This disorder occur because of mutation in one of the gene present on the X chromosome.Red green colorblindness is a X linked recessive disorder.Male carries one X chromosome and one Y chromosome, whereas Female carries two X chromosomes.So,If gene present on the X chromosome in male is mutated, he becomes colorblind,On the other hand if mutation occur in gene present on one of the X chromosome, she becomes the carrier,Female only become colour blind ,if gene present on both of X chromosomes are mutated,but it is very rare case. In the above diagram ,pedigree is shown for the colour blindness in a family. Here, square represents male ,circle represents Female.Darker square indicates that male is affected, whereas darker circle indicates that female is affected by colour blindness.Dot inside circle represents that female is carrier of the disease.Here, Genotype of A is XcX, This indicates that female is carrier for colour blindness ,as on mating with colour blind male ,she produces two daughters in which one is colour blind and other is carrier, which is only possible if mother is carrier for the gene responsible for colorblindness. Genotype of B is XY,This indicates that male is normal. Genotype of C is XcX,This indicates that female is carrier for the disease,as dot inside circle represent carrier female for the disease. Genotype of D is XY,This indicates that male is normal. Genotype of E is XY,This indicates that male is normal,as father is normal and mother is carrier. Genotype of F is XX,This indicates that female is normal. Genotype of G is XX,This indicates that female is normal. Genotype of H is XcY,This indicates that male is colorblind,as mother of this male is colorblind and this male receives ,one X chromosome from the mother ,as it carries the mutated gene, it results in male which is colorblind.
